Volume SnapMirror protects SnapVault secondaries by creating SnapMirror relationships to migrate data from the volumes on the SnapVault secondary storage system to volumes on a remote (tertiary) storage system running Data ONTAP. SnapMirror provides an exact replica of the SnapVault secondary data on the tertiary storage system.
The advantage of protecting SnapVault secondaries using volume SnapMirror is that soft lock support enables you to continue SnapVault relationships between the original SnapVault primary storage system and the tertiary storage system, without initial baseline transfers.
To deploy this solution, ensure that you use the appropriate licenses for using SnapMirror and SnapVault. You cannot execute SnapVault commands on the new secondary system (which is also a SnapMirror destination) if you do not license sv_ontap_sec on this tertiary system.
For example, if your SnapVault secondary storage system becomes unusable because of a disaster, you can manually redirect your next SnapVault transfers to the tertiary storage system instead of the unusable secondary storage system. Your tertiary storage system becomes the new SnapVault secondary storage system, and your SnapVault transfers continue, using the latest Snapshot copy common to both the primary and the tertiary storage systems.
